My late Holiday gift to you:

I have bought and love Cards Against Humanity (www.cardsagainsthumanity.com).

It is an adult version of Apples to Apples and calls itself "A Party Game for Horrible People". It has sold out each time it hits Amazon.

But what people don't realize is that you can download the game and print it yourself with the game creator's blessing (and instructions):

It ain't right. You have been warned. :)
